More than one tool in your toolbox

When it comes to improving your business you need to have more than one tool in your toolbox.
 
Although we often start with getting the pricing right we also like to look at other things. My books give you some examples of these but they are broadly:
 
Efficiencies – implement systems, checklists, automation and delegation
 
People – get the right people in the right place, suitably trained and equipped, and all pulling in the right direction
 
Marketing – a baseline level of marketing going on at all times so that you have clients/work already lined up for quieter periods
 
What else do you do to improve your business?
